Description
Technical Field
The invention relates to the technical field of machining, in particular to a paint spraying device for an inner wall of a round pipe for an automobile.
Background
The paint spraying and coating of the metal surface is an important metal corrosion prevention and maintenance means. The good paint spraying protective layer keeps continuous, complete and undamaged, has good combination, and can be a barrier for inhibiting corrosive media from invading.
When the existing equipment for spraying paint is used for spraying paint on the pipe, the paint is difficult to be sprayed on the inner wall of the pipe, so that the inner wall of the pipe cannot be uniformly covered with paint; when the inner wall of the pipe is manually sprayed, due to the narrow space in the pipe, the inner wall of the pipe cannot be uniformly covered with paint due to manual operation, the pipe usually starts to corrode from the inside when in use, and particularly, the iron pipe does not have corrosion on the appearance but is corroded inside.
Disclosure of Invention
The invention aims to provide a paint spraying device for the inner wall of a round pipe for an automobile, which aims to solve the problem that paint spraying equipment in the prior art cannot uniformly spray paint on the inner wall of the pipe.
In order to achieve the above purpose, the basic scheme of the invention is as follows: a paint spraying device for the inner wall of a round pipe for an automobile comprises a rack, wherein a base and a motor are arranged in the rack, a central column is fixedly connected to the base, the central column is rotatably connected with a rotating shaft, the rotating shaft is coaxially and fixedly connected with a grooved pulley, a plurality of radial grooves are formed in the grooved pulley, a placing disc is fixedly connected to the end part of the rotating shaft, and a clamping device for clamping the round pipe is arranged on the placing disc; the left side and the right side of the base are respectively and rotatably connected with a first rotating rod and a second rotating rod, one ends, far away from the base, of the first rotating rod and the second rotating rod are respectively connected with a supporting rod, the end portions of the supporting rods are connected with cylindrical pins used for being matched with radial grooves, the first rotating rod is coaxially connected with a first gear, the second rotating rod is coaxially connected with a second gear, the first gear and the second gear are meshed with a third gear together, and the third gear is coaxially connected with an output shaft of a motor; still be connected with vertical dead lever in the frame, the dead lever lower extreme is connected with paint gun and cylinder brush, the cylinder brush offsets with the pipe and sets up.
The technical principle of the scheme is as follows: when the device is used, a round pipe to be painted is placed on the placing plate, the round pipe is clamped and fixed by the clamping device, and at the moment, the fixing rod does not extend into the round pipe; then, a motor is started, an output shaft of the motor drives a third gear to rotate, the third gear drives a first gear to rotate in the reverse direction of the first gear, the first gear drives a first rotating rod coaxially connected with the first gear to rotate synchronously, a cylindrical pin on the first rotating rod continuously rotates by taking the first rotating rod as a central shaft and intermittently rotates into one radial groove of a grooved pulley, the grooved pulley rotates at a certain angle by the thrust of the cylindrical pin, meanwhile, the third gear drives a second gear to rotate in the same direction as the first gear, the second gear drives a second rotating rod coaxially connected with the second gear to rotate synchronously, the cylindrical pin on the second rotating rod rotates by taking the second rotating rod as the central shaft and intermittently rotates into one radial groove of the grooved pulley, and the grooved pulley continues to rotate at a certain angle by the thrust of the cylindrical pin; the cylindrical pin on first dwang and the second dwang promotes the sheave in turn and rotates constantly, take place to rotate with the coaxial fixed connection's of sheave rotation axis synchronization, when the rotation axis is pivoted, the rotation axis is for center post upward movement gradually, connect and place a set synchronous rotation and the rebound at the rotation axis tip, and drive and place the pipe synchronous rotation and the rebound on the dish, make the dead lever stretch into in the pipe gradually, the spray gun carries out the spraying from top to bottom to the pipe inner wall, the cylinder brush evenly paints to the pipe inner wall that has sprayed paint.
The beneficial effect of this scheme: 1. the paint spraying gun sprays the inner wall of the circular tube from top to bottom, and the roller brush uniformly coats the inner wall of the circular tube sprayed with the paint, so that each part of the inner wall of the circular tube is covered with the paint and is not corroded. 2. The grooved pulley is alternately pushed to rotate by the cylindrical pins on the first rotating rod and the second rotating rod, so that the circular tube on the placing plate slowly rotates and rises, and the fixed rod slowly extends into the circular tube, so that the paint spraying gun can fully spray the inner wall of the circular tube. 3. Utilize the dead lever to stretch into in the pipe, the spray gun carries out the spraying to the pipe inner wall, when having overcome manual operation, because intraductal space is narrow and small, manual operation also can lead to the problem that the coating of tubular product inner wall can not be even coats the paint.
Further, clamping device includes the centre gripping lantern ring, the bottom of the centre gripping lantern ring with place a set fixed connection, threaded connection has a plurality of threaded rods on the centre gripping lantern ring, the threaded rod stretches into the inboard one end fixedly connected with arc grip block of the centre gripping lantern ring, the surface coating of arc grip block has the polyester rubber layer. The arc grip block of screw rod tip carries out the centre gripping to the pipe, prevents that the pipe from taking place relative movement at the in-process that sprays paint with placing the dish, and the polyester rubber layer on arc grip block surface can protect the surface of pipe, prevents that it from being worn and torn, and the polyester rubber layer can increase the frictional force on arc grip block and pipe surface simultaneously, further prevents that the pipe from taking place to remove.
Further, a cavity is formed in the fixed rod, a through hole communicated with the cavity is formed in the side wall of the fixed rod, a fan is connected to the upper end of the fixed rod, and the fan is fixedly installed on the rack. The fan blows air constantly in to the cavity of dead lever, and the air gushes to the inner wall that scribbles the pipe of paint from the through-hole of dead lever lateral wall, the solidification of paint with higher speed.
Further, the surface of the placing disc is provided with an annular recovery groove. When the spray gun sprays the inner wall of the circular tube, the sprayed paint is too much, so that the excessive paint flows into the annular recycling groove on the placing disc from top to bottom along the inner wall of the circular tube, redundant paint can be recycled, and waste is avoided.
Furthermore, a power supply electrically connected with the motor is further arranged on the rack, a key switch used for controlling the power on and off is arranged on the placing disc, and the key switch is electrically connected with the power supply. The pipe constantly rotates and upward movement, and the dead lever moves down for the pipe, conflicts the key switch who places on the dish until the tip of dead lever, and key switch control power outage, motor stall, and at this moment, it shows that the spray gun has accomplished the comprehensive spraying from top to bottom to the pipe inner wall.
Further, the transmission ratio of the first gear, the second gear and the third gear is 1:1: 1. The third gear is a driving gear and drives the second gear and the third gear to rotate respectively, the rotating speed is the same, and the transmission is more stable.
